The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks.
We’re looking at a solid run of swell at Lakey Pipe (Lakai-Pipe) starting right away. This is a reef break, so it’s strictly for the experienced crew. The water temp is about normal for this time of year.
The first standout is the whole window from Wednesday the 5th through the end of the first week. The energy is strong, with readings in the thousands to over 3000, meaning plenty of power. Winds are light and cross-offshore, keeping the surface clean. The swell is coming from the SW, which is the perfect direction for this spot.
Wednesday the 5th kicks off with 5ft SW swell at 14 seconds – that’s a long period groundswell, so expect proper lines. The wind is a light cross-off from the SE, and the wave energy is pumping (1109). It’s clean, but the size is for the experienced.
Thursday the 6th sees the swell bump to 7ft, and the period stretches to 18 seconds – very long groundswell. The energy jumps to 2462. The wind stays clean. Getting serious.
Friday the 7th is where it gets real. The swell hits 7ft in the morning, then 8ft in the afternoon. The period is a solid 16 seconds. The afternoon session has a combined energy of 3217. This is powerful reef surf. Not for beginners.
Saturday the 8th holds the size at 8ft with light winds. The energy is massive at 3504. This is the best of the first week. For experienced surfers, a dream.
Sunday the 9th the swell drops slightly to 8ft, but the period stays at 16 seconds. Energy still over 2500. Still excellent.
Monday the 10th has a slightly smaller 6ft swell, but the period is 15 seconds. The wind is light and cross-off. Energy is 2154. Still a great option.
Tuesday the 11th is another standout. The swell jumps back to 8ft with a 17-18 second period. Energy over 4000. This is serious groundswell. The wind is clean.
After that, the swell drops a bit through the middle of the week, but stays in the 5ft to 6ft range with good periods. The wind remains mostly light and cross-off. Energy in the 1600-2000 range, still very surfable.
Thursday the 18th things get interesting again. The swell jumps to 8ft, then on Friday the 19th and Saturday the 20th it hits 10ft. Energy over 4400. But the wind turns cross-shore, and the wave comment says it might be too big for this break. That’s a warning. For a reef break, that much power with cross-shore wind could get messy and dangerous. Only top-tier experts.
The final clear standout is Monday the 11th, with that perfect 8ft, 18-second groundswell and light, clean winds. That’s the session to circle.
Crowds are noted as "often" here, so expect company, especially on the good days. The consistency is solid.
Overall, this is a top-tier run for Lakey Pipe. The first week is pure gold for the experienced. The second week has a couple of big, dangerous days. Stay sharp.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
